What is ECN-2?

By March 23, 2024No Comments

We would like to inform everyone that we are now developing ECN-2 films.

To those who don’t know ECN-2 is, ECN simply stands for Eastman Color Negative. It was a processing system that evolved into ECN-2 when research enabled faster and more environmentally friendly development processes (and thus faster photo lab turnaround time!). As a result, ECN-2 became the industry standard for all current motion picture color negative development till today. In short, it provides a cinematic look that you see in most movies today (due to the REMJET layer being removed).

The reason why the ECN-2 process exist is because the remjet layer on the back of the film provides protection from scratches, static and halation around highlights. This black coating on the film must be removed before development. It is not intended to be processed in the C-41 color negative development process. Even though the process may be similar to C-41 development, there is an additional step that differentiates the two. ECN-2 process includes what is called a prebath – this removes the adhesive holding a layer of black carbon off the backing of the film, or remjet layer.

The remjet layer is on the back of this film for multiple reasons:

1) It acts as a layer that significantly dampens halation (light passing through the film and bouncing back into the emulsion).

2) The remjet layer displaces static build-up. In the motion picture industry, film pulls through a camera at 24 frames per second (or more). This rapid movement through the camera can build up static. When static discharges on film, it creates a spark that shows up on your film.

Since we now offer ECN-2 development, we are also offering Kodak Vision 3 250D film stock in 35mm.

If you’re interested in getting a roll of Kodak Vision 3 250D or you want to drop off a roll of ECN, stop by our shop to purchase yours today.
